Abstract:
PROBLEM TO BE SOLVED: To provide flexible tubing that reduces environmental and health concerns associated with PVC-based flexible compositions.SOLUTION: A hose may have two or more layers. A flexible tube 200, which is flexible tubing including a bulk layer 202 and a liner 204, includes a first layer 204 comprising a polyolefin material having a flexural modulus of not greater than 150 MPa and includes a second layer 202 directly bonded to and in direct contact with the first layer 204. The second layer 202 comprises a blend of propylenic polymer and styrenic block copolymer.

PROBLEM TO BE SOLVED: To provide multi-layered rubber tubing with which the capture of hydrocarbons permeating through a tube wall of an engine non-automotive fuel line meets the most rigorous requirement of small California Air Resources Board (CARB).SOLUTION: A non-conducting flexible tubular fuel hose for transport of volatile hydrocarbons comprises: (a) an inner layer of a polyvinylidene difluoride (PVDF) polymer or a polyvinylidene difluoride copolymer; (b) an intermediate thermoplastic polyurethane (TPU) layer extruded in a tubular form over the inner PVDF layer; and (c) a polyvinyl chloride polymer extruded in a tubular form over the outside surface of the intermediate layer and being coextensive with the surface.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved perfluoropolymer composite that uses a blend of a perfluoropolymer (such as PTFE) and a silicone polymer.SOLUTION: By coating a substrate 602, such as glass fiber fabric, with a blend of a perfluoropolymer and a silicone polymer, an adhesive layer 608 can be bonded either directly to the surface of the perfluoropolymer composite 600 or to a perfluoropolymer composite that has been primed without the need to have otherwise treated the perfluoropolymer surface, either by etching or by the deposition of an intermediate coating containing a colloidal silica or other similar agents, to make the surface bondable.
Abstract:
PROBLEM TO BE SOLVED: To provide a favorable composition that contains polyalkylsiloxane and a radiation resistant component, and to provide a medical device formed of the same.SOLUTION: This invention relates to a polymer material formed of the composition that contains the polyalkylsiloxane and the radiation resistant component. The content of the radiation resistant component is about 0.1 to about 20 wt.% based on the mass of the polyalkylsiloxane.
